I agree it would be best to have the same size. What are the recommendations
for tire rotation nowadays? For example, could I rotate the spare into the
regular rotation or do right-side tires have to stay on the right side and vice
versa? Seems like I read somewhere that the direction of rotation has to stay
the same.

You might want to check with the manufacturer to see how much difference is
acceptable. I have an all-wheel drive car, and there is a specification
regarding how close to identical the diameter of each tire must be.
But since you've only got two driven wheels, an spare that doesn't match the
rears could always be put on the front, and one of the fronts moved to the
rear, in a pinch.
Probably better to have the right size spare...

Jim,
Seems to me the rule of thumb should be to use the same diameter tire for a
spare regarding a posi rear. Might be hard on the clutch pack in a limited slip
to run any distance with mismatched set. A true posi, where there is no slip
wouldn't be able to handle it very long as you'd probably bust an axle or the
differential before long. I would personally get the same diameter for a
spare.--wayne
